Definitions

  • the field of invention is switch lever lock-outs for locking switch levers in a desired position, and more particularly to switch lever lock-outs which engage holes formed in switch cavity walls
  • Switches are used in many applications to control the flow of electrical energy.
  • the switches can be used to redirect electrical energy from one circuit to another, and can be used to stop the flow of electrical energy through a circuit. In both cases the circuits become de-energized, that is without a voltage.
  • One particular type of switch is a circuit breaker which cuts off the flow of electrical energy when the flow of electrical energy through the switch exceeds a predetermined value.
  • Many of these circuit breakers include a switch tongue movable between an "On” position and an “Off' position. Walls adjacent the switch tongue between the "On” and “Off” positions define a switch tongue cavity. Opposing holes in the wall can receive pins to prevent movement of the switch tongue.
  • circuit breaker To interconnect the flow of electrical energy through a circuit when the circuit, or electrical components connected thereto, require maintenance.
  • the circuit breaker is often remote from the location requiring maintenance. Therefore, it is desirable to lock out the circuit breaker to prevent an individual from inadvertently energizing the circuit while maintenance is being performed.
  • a circuit breaker lock-out assembly for locking out a circuit breaker including a tongue moveable between a pair of walls having holes formed therein is known from EP 0 604 331 A1 .
  • This known circuit breaker comprises a locking pin having two flexible arms equipped with spigots arranged to enter the holes when the tongue is in one of its stable positions.
  • the known circuit breaker is arranged to be fitted on a case when the tongue is in one or the other of its stable position.
  • a lever is movable between a first up position and a second down position. The lever comprises a first opening allowing a locking padlock to pass when the lever is moved to the second position, and to make the spigots enter the holes.
  • the lever is supported by a cover which is provided with a second opening aligned with the first opening when the lever is in the second position and designed for the locking padlock to be passed through.
  • the locking pin is fitted in the cover and comprises a U-shaped element. The branches of the U are extended by the flexible arms whose ends bear the spigots.
  • a known circuit breaker lock-out disclosed in French Patent No. 2,424,619 shows leaf springs having pins which engage the inwardly opening holes of the switch tongue cavity walls.
  • operation of the lock-out is difficult, and requires two hands to engage and disengage the lock-out from the circuit breaker. Therefore, a need exists for an effective, easy to use, circuit breaker lock-out assembly.
  • the present invention provides a circuit breaker lock-out assembly which is engageable with a circuit breaker.
  • the assembly includes a body having a top and a bottom joined by walls. The walls define a passageway extending from the body top to the body bottom.
  • a button having one end extending into the body passageway through the body top is movable between a lock position and an unlock position.
  • a pair of leaf springs is fixed to the button, and extends through the body passageway.
  • a nose extends from the body bottom, and is engageable with the leaf springs.
  • a pin extends from each of the leaf springs.
  • Each pin is engageable with a hole formed in the circuit breaker walls adjacent the switch tongue, wherein slidable movement of the button toward at least one of the lock position and unlock position engages the leaf spring with the nose to move each pin relative to the hole formed in the wall.
  • Said pair of leaf springs is firmly fixed to said button, said nose is extending from said body bottom, said nose is rigidly fixed to the body or is formed as an integral part of the body.
  • An objective of the present invention is to provide a circuit breaker lock-out assembly which is easily operated. This objective is accomplished by providing leaf springs fixed to a slidable button and arms which extend from the assembly body which are engageable with user fingers to allow single handed operation of the circuit breaker lock-out assembly.

  • the button 20 slidably engages the body walls 36, 38, 40 for slidable movement in the passageway 42 along the assembly axis 60.
  • the button 20 is slid,able between a lock position (shown in Figs. 1 and 3 ) and an unlock position (shown in Figs. 2 and 4 ). In the lock position, the button 20 is only partially inserted into the body passageway 42 In the unlock position, the button 20 is inserted further into the body passageway 42 than in the lock position.
  • the button cleat 52 extends from the button base front face 68 into the body cleat slide opening 46.
  • the button cleat 52 engages the cleat slide upper end 48 to prevent the base bottom 64 from sliding out of the passageway 42 through the body top 16.
  • a second button cleat (not shown) extends from the base rear face, and extends into a cleat slide opening formed in the body rear wall 38.
  • An aperture 72 formed through the button base 62 from the front face 68 to the rear face is exposed when the button 20 is in the lock position.
  • a pin member such as a lock hasp, can be slipped through the aperture 72 to prevent the button 20 from being moved to the unlock position.
  • a cavity 74 formed in the base front face 68 receives the pair of leaf springs 22 which extend past the base bottom 64.
  • the leaf springs 22 engage stops 76 extending substantially perpendicular to the axis 60.
  • the stops 76 prevents the leaf springs 22 from slipping axially in the cavity 74.
  • a cavity 74 having stops 76 to prevent axial movement of the leaf springs 22 is shown, other methods for fixing the leaf springs 22 to the button 20 can be used, such as forming a groove in the base front face to receive the leaf springs, embedding a proximal end of each leaf spring in the body, and the like, without departing from the scope of the present invention.
  • the leaf springs 22 are fixed to the button 20, and extend through the body passageway 42 past the button base bottom 18.
